CME Analysis Information (for CME activity ID: 2026-05-23T06:48:00-CME-001)
Measurement Creation Time: 2026-05-23T15:30Z
Catalog: M2M_CATALOG
Data Level: 0 (0=real-time, 1=real-time and checked by supervising forecaster, 2=retrospective science level data analysis)
Use as primary measurement: false
Measurement Technique: SWPC_CAT

Detecting Instruments:

SOHO: LASCO/C3

Image Type: running difference
Speed (km/s): 368.0
Speed measured at height (Rs): 16.7
Type: S
Direction (LON/LAT in HEEQ): 105.0/ 25.0
Half Angular Width (degree): 29.0
Minor Half-width (degree): None Entered
Tilt (degree): None Entered
Time@21.5: 2026-05-23T17:24Z
Info/Session URL: None Entered
Note:

A preliminary SOHO LASCO C3 analysis close to the approximate observed source of the CME around N18W105. This does not match the STEREO A COR2 front for full triangulation (see other CME analysis note), but is presented due to the magnitude of the other analysis' deflection.
